### Claim 9 (depends on 2)

The cooking system of claim 2, further comprising an insert for supporting a food item in said hollow chamber, wherein said insert is positionable within said food container to form an annulus between an inner wall of said food container and an outer wall of said insert.

### Claim 10 (depends on 9)

The cooking system of claim 9, wherein said insert further comprises a base and an open end, said base including a plurality of apertures that allow fluid to flow through said base.

### Claim 11 (depends on 9)

The cooking system of claim 9, further including a diffuser disposed beneath said base, said diffuser including at least one vane configured to impart rotation to fluid circulating through said plurality of apertures during said dry cooking mode.

### Claim 12 (depends on 11)

The cooking system of claim 11, wherein said insert is disposed in said food container, said food container is received in said hollow chamber, and further including a fan with said heating element in said second lid, said fan being positioned to move heated air relatively downward through said annulus, relatively horizontally across a lower surface of said food container, and relatively upward through said diffuser and said plurality of apertures of said base, wherein said fan is positioned to draw air relatively upward through said insert and through said at least one heating element in said dry cooking mode.

### Claim 13 (depends on 12)

The cooking system of claim 12, wherein said food container includes an upward facing lower surface that is curved upward in a direction of an upper opening of said food container, and said diffuser includes downward facing lower surface that is curved or sloped to conform to said upward facing lower surface of said food container.

### Claim 14 (depends on 2)

The cooking system of claim 2, wherein said first lid abuts said housing about a substantial entirety of said upper surface thereof when said first lid is in said closed position, and/or wherein said housing is configured to surround food container around a substantial entirety of at least a portion thereof when said food container is received within said hollow chamber.

### Claim 15
